Improvement in harness saddle-trees

Letters Patent No. 111,502, dated January 31, 1871.`

IMPROVEMENT IN HARNESS SADDLE-TREES.

The Schedule referred to in these Letters Patent and making part of the seme.

To all whom it may concern Be it known that I, PHILIP H. W1EDERsUM, of the' city, county, and State of New York, have invente'd certain new and useful Improvements in Harness Saddle-Trees; and do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing and` to the letters of reference marked-thereon.

rEhe nature of my invention consists in the const-ructiou andarrangement of a harness saddle-tree, as will be hereinafter fully set forth.

In Vorder to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation referring to the aunexed'drawing which forms a part of this specification, and in which- Figure 1 is a side view of my saddle-tree;

Figure 2 is a longitudinal vert-ical section;

Figure 3 is a transverse vertical section through liue a: x, fig. l; and

Figure 4 is a similar lsection through line y y, g. 1.

My saddle-tree is composed of two metal castings or plates, A and B,

. The plate A is provided with two ribs, fr fr', running across the entire plate parallel with each other,

'and forming between them a groove or smooth recess,

in which the back band is allowed to slide-freely.

n The front central portion of the plate-A is made to bulge upward, as shown iu fig. 3, so that under no circumstances can the back-bone of the horse come in contact with the same, therebypreventing injuryV to the horse. V

Onv the interior of the plate A, at a suitable distance above the lower edge, is a rectangular recess, a,'in thev center of which there is a square hole ot' suitable dimensions. l

v The` plateis hereformed with a swell ou its ex- ;t'erior to form a box, b, which receivesV the body of a square nut, G, said nut being provided with a ange orplate, `which fits in the recess a, and is there secured by rivets.

Itis, ofcourse, understood that the square n ut Gn is inserted from underneath, and the terret is then screwed into said nut.

If, by anymeaus, the rivets securing the plate 7' in its position should become loose orbrokeu, the terret will not turn around, as the nut G is square and held in the square hole and box b on the main plate A; and if the threads in the nut G should become worn out, the kplate j, with the uut,c'an be-slipp'ed out without removing the covering of the saddle-tree, and another inserted in its place without riveting, as the box and nut, being square, will retain it in position;

These are the main advantages over the usual round nut in common use, although there are others which I deem it not necessary to mention here.

The recess a, with the' hnle. and box b, may be made between the ribs vr 1", or in front of rib r, or in both places, as represent-ed in the drawing.

Near the rear endl'of the upper portion of the plate A is a round boss, @provided with a hole for the reception ofa screw, D, and inthe forward portion there is a hole for the reception of the screw E, aud ou the exterior of the latter portion there is a piece of leather, F, fastened by rivets, and provided with a square hole, g, 4into which the hole e opens. Y

It might here be mentioned that on the saddle-trees new in common use a piece of leather is fastened extending along the entire front edge of the tree.

I use merely a block or small piece,'F, of leather, in the center, and also a small strip on `each side,

'thereby lessening the expense, as scraps of leather advantage as a continuous strip The plate B, which forms the eantle, has' a boss, j, formed on its under side, which, when in place, rests on thefboss formed on the plate A, and is provided with a tapped hole to receive the screw D, by Vwhich the rear portions of the two plates 'are secured together.

The cantle has also formed on its under side, near its forward end, a ysquare box, It, which fits into the hitherto deemed worthless may be used with. equal hole g'in the leather F, and up againstthe front of the rib r on the plate-A.

The check-hook O is formed with a concave bearing surface, and hasproject-ing therefrom a square boss, l, which is provided with ajtapped hole, and fits in the box It on the cantle B, and receives-the shank ofthe screw E, by which the whole is firmly secured together.

f The square projection l ou the check hook prevents the same from turning if lthe .screw should become' loose by any means, whiclris a decided advantage `over the usual mode of fastening, as it'ofteu happens thatthe check-hook becomes loose and turns as it on l a pivot. V

It is, of course, not absolutely necessary that the boss Z should be on the under side of the check-hook. It may be on the upper side of' the lower end, which end is then inserted from underneath the front edge Vof the main .plate A, the boss l passing 'upward,'and the screw E is inserted from the top;

Having thus fully describedmy invention,

Vhat I claim as new, and `desire toA secure by Letters Patent, is

l. The cantle-plate B, provided -with' the square box kaas and for the purpose set forth.

2. In combination with the cantlefplate B', provided with the square box k, the rib fr, as and for the pur poses set forth.
